Hi again folks. I had replaced the belts on my Sears 30" mid engine mower. It seemed ok but now it is slowing to a stop. :(

I'm not sure how to tell if it's the transmission or the variator. I have been reading a few things around the net trying to figure out if the variator could be causing the stoppage. I can drive for about 15-20 minutes and then no-go. I have not ever lubed it and swear I smell rubber when it stops.

Can anyone elaborate or clue me in to what is happening? :confused:

Thanks again, rbee.

It sounds like maybe one of the belts is too tight? That could be why you're smelling the burnt rubber and why it would come to a stop.

Or the flip side to that being they are a little too loose and after they warmup up they expand length wise just enough to loose grip.

Either way a tension adjustment might just be the key to it. If in doubt you could try adjusting it a small amount both ways and see if it makes any difference.
